This I00 50separately from and independently of the is a very advantageousconstruction, as it mechanism for manipulating the web to he will allowthe main web to run very easily and smoothly through the printingmechanism.

The combing of the first impression-cylinder is not so material and maybe neglected, as the first impression-cylinder turns against a cleanside of the web and not against a freshly-printed side of the web, aswould be the case if no offset-web was used between the web to beprinted and the second impression-cylinder.

I may use the same adjusting mechanism to adjust the length of a sheetprinted on the main web and the feed of the offset-web, and one way ofcarrying this out is by the gearing shown in this case.

The printing-couples are geared together by gears 47, 48, 50, 49, 51,52, and 53, as shown. A gear 54 meshes into gear 53, and gear 54: isdriven from a gear 56, mounted on a shaft 55, which Iterm the main shaftof the machine. The gear 56 is driven by a pinion 57 from a power-shaft58. The end of the shaft 55 is keyed, and fitting on the end of the sameis a change gear and cam 59 and 60, preferably made in one integralpiece, and from this changeable piece the entire web-manipulatingmechanisms forboth the web to be printed and the offset-web are driven.The change gear and cam maybe varied by removing the nut 550.

A sweep 61, having an extending arm 62, is mounted upon a shaft 06 andcarries an intermediate 64, which can be set by means of clamping device63 to engage whatever sized gear is put upon the shaft 55. Thisintermediate engages a gear 65, also turning with which isa bevel-gear07, which meshes with and drives a bevel-pinion 08, secured upon theshaft 69, mounted in bearings 70, 71,

and 72.

On one end of the shaft 69 is arranged a bevel-gear 73, which mesheswith abevel-gear 74 on shaft 75, arranged in bearings 76, 90, and 96, asshown. From this shaft, by means of bevel-gears 77 and 78 and gears 7 9,780, and 80, the feeding-in device for the main web is continuouslydriven, and by means of bevelgears 91 and 92 and gears 93, 94c, and 95the feeding-in device for the offset-web is continuously driven. On theother end of the shaft 69 is arranged a bevel-pinion 81, which mesheswith and drives a pinion 82, secured on shaft 83, mounted in bearings 71and 84. From this shaft, by means of bevel-pinions 85 and 86 and gears87, 88, and 89, the continuously-running feeding-outdevice for the mainweb is driven. Arranged on the shaft 75 is a bevel-pinion 7 G0, whichdrives a bevel-pinion 97, and by means of gears 98, 99, and thecontinuously-running feeding-out device for the offset-web is driven.Meshing with the gear 74: is a bevel-pinion 101, arranged on the end ofthe shaft 102, mounted in brackets 103 and 104, and arranged on thisshaft is a bevel-pinion 105, which meshes with a bevelpinion 106, and bymeans of gears 107, 108, and 109 the rewinding device for the offsetwebis driven. The loopers 37 and 40 are mounted in common brackets 41,arranged in the ways 110 in the main frame, as shown. The arms 16 havesuitable adjustable connections 111, to which arms 112 are connected.Bearing against the cam 60 is a roller 113, mounted in the arm 114 ofthe bell-crank lever 114 115. This bell-crank lever is mounted upon ashaft 123, which extends across the press and has an arm 115 arranged onthe oppoiste side of the same, similar to the arm 115 shown, so that theloopers are operated simultaneously from both sides of the machine orsquared. Also extending from the bell-crank lever is an arm 116, whichconnects by link 119 to a bell-crank lever 120 12l,mounted on a shaft122, which bell-crank lever is attached to one arm 30. An arm 121 ispreferably arranged on the back side of the shaft 122 and connected tothe other arm 30, so that the feeding-out looper 27 will be operatedfrom both ends or squared. A spring 117 is arranged between the arm 116and a station ary point 118 and serves to keep the roller 113 againstthe cam 60, as shown.

The change cam and gear may be removed, if desired, and another cam andgear, as 560 570, may be substituted. By this gearing, which has beendescribed at length, it will be seen that the entire web-manipulatingmechanisms, both for the web to be printed and the oifset-web, aredriven entirely from the change gear and cam, so that by changing onepiece the length of the sheet to be printed is varied, and at the sametime the proper action of the offset'web is insured.

It also will be seen that the means for controlling and intermittinglywithholding the offset-web are entirely independent from the means forwithholding or controlling the action of the main web, so that thestrain put on the offset web will not'affect either the web to beprinted or its controlling mechanism.

Many other arrangements of gearing may be made to carr T out thepurposes of my in vention.

My invention may be applied to a press 111 which the web to be printedis withheld 01'111 which only one web or a portion of the web to beprinted is withheld.

The details and arrangements herein de scribed may be greatly varied bya skilled mechanic without departing from the spirit of my invention.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The combination in a rotary printingpress, of controlling-means forintermittingly withholding the web to be printed, an oifsetwebinterposed between the web to be printed and the secondimpression-surface and separate controlling means for intermittinglywithholding the offset-web, substantially as described.

2. The combination in a rotary printingpress of controlling means forintermittingly withholding the web to be printed, an offsetwebinterposed between the Web to be printed and the secondimpression-surface and separate controlling means for intermittinglywithholding the oiisetweb so arranged that the web to be printed and theoffset-web will move in harmony, substantially as described.

3. The combination with a web-printing press in which the web to beprinted is intermittingly withheld, of an offset-web interposed betweenthe web to be printed and the second impression surface, and means forcontrolling the oitset-web so that the same will move in harmony withthe main web, consistingofcontinuously-running feeding-in andfeeding-out devices and looping devices, substantially as described.

4. The combination with a web-printing press in which the web to beprinted runs intermittingly, of an offset-web interposed between the webto be printed and the second impression-surface,means whereby the lengthof the sheet printed maybe varied and means whereby the offset-web maybe adjusted to always move in unison with the web to be printed,substantially as described.

5. The combination with a rotary webprinting press in which the web tobe printed is withheld during the non-impression period, of anofiset-web interposed between the web to be printed and thesecondimpression-surface and a single adjusting mechanism arranged tovary the length of the sheet that maybe printed and to adjust themovement of the ofiset-web so that the offsetweb will al ways move inunison with the web to be printed, substantially as described.

6. The combination with a rotary web printing press, of controllingmechanism for the web to be printed consisting of continuously-runningfeeding-in and feeding-out devices and devices arranged so that the mainweb may be withheld during a non-impression period, an offset-webinterposed between the web to be printed and the secondimpression-cylinder, controlling mechanism for the offset-web,consisting of continuouslyrunning feeding-in and feeding-out devices andloopers, and a single adjusting mechanism adapted to vary the speed andaction of the controlling mechanism of both the web to be printed andthe oitset-web, substantially as described.

7. The combination with a rotary webprinting press, of gearing wherebythe printing-couples will be continuously rotated, mechanism forwithholding the web to be printed during a non-impression period, anoffset-web interposed between the web to be printed and the secondimpression-cylinder, controlling mechanism for the offset-web arrangedso that the offset-web may move in harmony with the web to be printed,and a single adjusting mechanism adapted to vary the length of the sheetprinted and to adjust the action of the offset-web so that the same willalways move in unison with the web to be printed, substantially asdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
